I duplicate the failed test but I didn't have any errors. I tried with gcc 5.4.0, 8.3.0, -DCMAKE_BUILD_TYPE, -DBUILD_SHARED_LIBS=OFF and with the command line : ./SvtHevcEncApp -encMode 9 -i akiyo_cif.y4m -b test.h265 -lp 2 (-asm 0)
Error is that the CPU they used was too slow so the test did not finish in time, you can probably ignore it
Hi @PierreIntel ,
I also reproduced the random hang issue at least once within 20 times, with and without the PR #460 applied, by the command line:
./SvtHevcEncApp -i akiyo_cif.y4m -b test1.h265 -lp 1
So the hang issue isn't due to your PR #460 , which looks good to me, and indeed improves the encoding performance for big resolutions. So please make sure that the playback of encoded bit streams is correct for other formats (YUV422/444) as well, and then we will go through the review and merging process for the PR. Thanks!
Hi @intelmark , @1480c1 , @tianjunwork ,
I checked that the random hang issue exists for long time since v1.3.0, with the akiyo_cif.y4m file or other YUV low resolution inputs (such as 352x288), at the stack:

Once you also confirm it, we need to open an issue to track and fix it. Thanks!
Hello @Austin-Hu , I verified the output files with an input in 422/444 and the option color-format 2/3, there are no errors and I can playback them correctly.
